The path from conventional skin care, organic cosmetics or bio cosmetics with not always matching ingredients towards the use of natural skin system technologies is a paradigm shift in classical and dermocosmetics. It can be described as revolutionary: with our solutions, we are investigating the structures of healthy skin barriers. Thus, our developments provide a decisive contribution to skin health.

Skin Health Management

We see ourselves as ideas forging solutions against stressed, barrier-disrupted skin. The focus is on skin health management at gct: Our scientists understand the key points in skin problems, address them and develop for people suffering from skin problems both short-term as lasting solutions.

Research and development on & with skin barrier

One of the root causes for many skin problems and resulting skin diseases is a disturbed skin barrier. Most currently used solutions usually address the symptoms. However, they neglect the interlocking of key mechanisms that control the skin disorder. But this is essential to achieve sustainable effects.


The patent-pending Ortholamellar technology (OLT) opens up new approaches: it provides the solutions for a variety of skin problems. The process targets the natural, healthy skin structure: its recovery and maintenance is achieved with the help of synergistically working ingredients and technologies.

System technology for self-regeneration of the skin

The biology of the skin forms the core of research and development. In doing so, we try to avoid substances which metabolically stress the skin (emulsifiers, preservatives, dyes or perfumes). Through continuous work on and with research, we are striving to lead the innovation leadership in the area of skin problem solutions. The overall target is to return the skin into its natural skin regeneration cycle.
